Display which notes are playing on the audition pads when in clip/keyboard view.

When composing with a MIDI keyboard or when zooming in on a section that doesn't have any notes yet, I often lose track of where I am in terms of note height. One thing that would help me overcome this would be that the audition pads on the left would light up whenever the synth of kit clip I am viewing is playing a specific note. This would help me in three different scenarios:
1) I made the beginning of a synth melody and would like to finish it. I am zoomed in on the second part while the melody is playing. I hear a note from the first part of the melody I want to repeat in the second part. Instead of having to locate the note by changing my view, I see the corresponding audition pad light up, showing me on which row the note is and allowing me to plop down a note without changing my view.
2) I have a MIDI keyboard connected and linked to a synth. I just jammed the right melody but would like to program it into the clip track rather than recording it (I'm not a great piano player, but find it easy to find the right notes on a keyboard). Instead of repeating the process of finding the right note on my MIDI keyboard and then on my Deluge, by having the audition pads light up when I play my MIDI keyboard I can immediately program in the right notes in the right row.
3) When I am in the keyboard view for a synth and a melody on that clip is already playing, I cannot see which notes are already playing. When recording a jam using the keyboard view, I might play notes that are only half steps away from notes that are already playing, causing unwanted dissonance. When I can see which notes are already played I can more easily find parts of the register that are unused but might sound nice.

The only implementation problem I see is that when you play a MIDI note that is outside the scale view of a clip, you have no way of showing that specific note on the audition pads. Otherwise I see many upsides to this feature.
